  • Matrix character modification information unique to a given font
    Patent number: 4993853
    Abstract: A matrix printer (1) or other imaging device in a memory (7) stores fonts of character data (11, 11') in defining bit maps for each character of the fonts. The memory also stores shift values for each font which vary with the nature of the font for double strike, emphasize, and combined double strike and emphasize, from which character bit maps are modified before printing by being shifted and overlayed. Improved images for double strike and emphasize are achieved, and the combined double strike and emphasize need not be the overlay of double strike and emphasize.
